Good news for egg lovers with type 1 or 2 diabetes: Your breakfast omelet is back on the menu.

Studies have shown that contrary to popular belief, dietary cholesterol from foods such as eggs has little effect on the body's blood cholesterol levels. The effect that consuming cholesterol-rich foods has on your cholesterol levels is also in part genetic.

One study estimated that only 30% of people respond to cholesterol in food. The remaining 70% have either no response to dietary cholesterol or are only slightly affected by it. The American Heart Association and diabetes experts recommend eating no more than four eggs a week for optimal health.
